Common Synology Data Loss Situations We Handle
From accidental deletion and RAID crashes to volume corruption, DSM failures, inaccessible NAS devices, and hard drive malfunctions, we recover data from all major Synology NAS data loss scenarios.
Multiple Drive Failure
When two or more drives in a Synology NAS fail simultaneously, the RAID or SHR volume can become inaccessible, jeopardising all stored data. This often happens due to power surges, manufacturing defects, or prolonged wear across drives from the same batch. Our engineering & innovation team employs specialised imaging techniques to recover data even in cases where multiple drives have failed. Contact Stellar Data Recovery before taking any DIY recovery steps.
Failed RAID Rebuild
A RAID rebuild can fail midway due to a bad sector, an incompatible replacement drive, or a second drive failing during the process, leaving your volume in a degraded or crashed state. Attempting another rebuild without professional diagnosis often exacerbates data loss. Our lab reconstructs RAID parameters and recovers files even from failed or interrupted rebuilds. Reach out to Stellar Data Recovery for a safe evaluation.
SHR Corruption
Unexpected power loss, firmware glitches, or improper disk replacement can leave your SHR volume unmountable in DSM. Since SHR uses a proprietary layout across mixed-capacity drives, generic recovery tools often fail or cause further damage. Our specialists have in-depth expertise in Synology's SHR architecture and can rebuild the logical structure to restore your files. Contact us before running any DSM repair tools.
Storage Pool Crash
A storage pool crash can occur due to metadata corruption, failing drives, or abrupt shutdowns, rendering all volumes within that pool inaccessible at once. Since a single pool often spans multiple volumes, the impact on business data can be severe. Our recovery process rebuilds pool metadata and extracts data volume by volume with minimal risk. Get in touch with Stellar Data Recovery to assess your storage pool.
Volume Corruption
Volume corruption on a Synology NAS can result from power failure, bad sectors, or file system errors, making data inaccessible. Running CHKDSK or other repair tools on a corrupted volume can permanently overwrite recoverable data. Our Engineering & Innovation team works directly from disk images to safely reconstruct the file system and retrieve your data. Contact us before attempting any DSM-based recovery.
Btrfs Metadata Corruption
Btrfs metadata corruption disrupts the checksums and tree structures that Synology relies on to track files, often triggering read-only mode or complete volume failure. Standard tools cannot repair Btrfs internals without specialised knowledge of its architecture. Our lab reconstructs damaged metadata trees and extracts intact files even from severely corrupted Btrfs volumes. Reach out to Stellar Data Recovery for an expert diagnosis.
Accidental Reinitialisation
Accidentally reinitialising a Synology NAS during setup or troubleshooting wipes volume configuration and can overwrite critical metadata needed to access existing data. The more the system is used after reinitialisation, the lower the chances of full recovery. Our engineers act quickly to reconstruct the original volume structure and recover your files. Contact us immediately if your NAS has been reinitialising by mistake.
DSM Upgrade Failure
A DSM firmware upgrade interrupted by a power outage or network drop can leave the operating system corrupted, sometimes taking storage pools and volumes offline with it. Reinstalling DSM without proper backup can trigger data loss. Our engineers recover data independently of DSM's state, ensuring your files are retrieved safely before any system reinstallation. Contact Stellar Data Recovery before reinstalling or resetting your NAS.
Motherboard Failure
When a Synology NAS motherboard fails due to power surges, component wear, or manufacturing defects, the unit may not power on even though the drives themselves remain healthy. Attempting to force-boot a damaged unit can risk further damage to the drives. Our specialists extract drives safely and recover data independently of the NAS hardware. Contact Stellar Data Recovery to retrieve your files without delay.
Wrong Drive Removed
Removing the wrong drive from a degraded RAID or SHR array can push an already vulnerable volume into complete failure, making all data inaccessible. Reinserting the drive without proper sequencing can cause further corruption. Our specialists analyse the array configuration and safely recover data even after an incorrect drive removal. Contact Stellar Data Recovery before attempting to reinsert any drives.
